PLATE-HOLDER.

SPECIFICATION forming part of Letters Patent No. 468,456, dated February9, 1892.

Application filed December 10, 1890. Serial No. 374,159- (No modelJ Toall whom it may concern:

Be it known that I, \VILLIAM Il. LEWIS, a citizen of the United States,and a resident of -l luntington, in the county of Suffolk and State ofNew York, have invented certain new and useful Improvements in Photo-Caineras, of which the following is a specification.

My invention relates to improvements in plate-holders specially designedfor use in photographic apparatus known as enlarging or reducingcameras, although it is applicable to use in other photographicapparatus as well; and it consists in devices whereby the negative orits equivalent may be held either in a vertical ora horizontal plane.

Figure 1 illustrates a rear View of the in vention. Fig. 2 illustrates asection on the line 00 .r of Fig. l.

A is the base of the camera.

B is the negative-holding frame.

M M are two strips of wood or like material, which are as long as one ofthe sides of the square opening in the rear of the frame B. They arepreferably each provided with one or more clips N N, which are adaptedto enter sockets or grooves 0 O in the inner face of the frame on allthe sides of the rear opening, and they are also shouldered at P I,which shoulders engage with a ledge or rabbet Q Q also made on all theinner sides of the opening in the frame. The shoulders I I extend acrossthe ends of the stripsM M, so that they .will engage with the rabbets QQ on the sides of the opening which are at right angles to those uponwhich the strips M M are placed, as the case may be.

R -R are springs movable on theirpivots S S, which confine the negativeor its equivalent in place, as now well understood.

From the foregoing it will be seen that the 40 strips M M may beinserted in either the vertical or the horizontal sides of the rearopening in the frame 13, and consequently the negative may be heldvertically or horizontally, as desired. The rabbets on the frame 13 andthe shoulders on the strips M M prevent the passage of light,-exceptthrough the negative.

I claim- A plate=h0lder comprising, essentially, an exterior frame theopening in which is a parallelogram and removable strips adapted tochange the contour of the opening in the frame by being interchangeablyfitted into any of its sides, substantially as set forth.

Signed at New York, in the county of New York and State of New York,this 2d day of December, A. D. 1800.
